And, someone that joined, reported that www.berkeleylug.com wasn't
working, but berkeleylug.com was working fine.
Poked into it a bit and ... egad, we were missing the IPv4 address
on www.berkeleylug.com. So, for folks lacking IPv6 it would outright
fail - anyway, added the missing - and all the authoritative
nameservers picked it up in short order.

Negative caching 'n all that - could take up to 24 to 48 hours
to be 100% effective Internet-wide.

In any case, for the web, berkeleylug.com is the canonical,
so http[s]://www.berkeleylug.com/ will redirect to https://berkeleylug.com/
(and preserving any path portion)

$ curl -I http://www.berkeleylug.com/whatever...

And, peeking over history (RCS) and such - looks like that was missing for a
long time. Likely got dropped at time of DNS migration off of
Google's DNS. Checking over RCS history, it's
missing back at least as far as 2019-05-07T08:23:45+0000.
